Dubstep

Dubstep is a genre of electronic dance music described as tightly coiled productions with overwhelming bass lines and reverberant drum patterns, clipped samples, and occasional vocals.
Dubstep's early roots are in the more experimental releases of UK garage producers, seeking to incorporate elements of drum and bass into the South London-based 2-step garage sound. The genre's feel is commonly dark; tracks frequently use a minor key and can feature dissonant harmonies such as the tritone interval within a riff. Read more on Last.fm.
